The Chelyabinsk superbolide was the largest known natural object to enter the Earth's atmosphere since the Tunguska event in 1908 and it has become a template to understand, manage and mitigate future impacts. Although the event has been documented in great detail, the actual pre-impact orbit of the parent body is still controversial. Here, we revisit this topic using an improved Monte Carlo approach that includes the coordinates of the impact point to compute the most probable solution for the…

Chasing the Chelyabinsk asteroid N-body style
On 2013 February 15 a small asteroid rammed against the atmosphere above the region of Chelyabinsk in Russia, producing the most powerful superbolide since the Tunguska event in 1908. Lacking proper…
Recent multi-kiloton impact events: are they truly random?
It is customarily assumed that Earth-striking meteoroids are completely random, and that all the impacts must be interpreted as uncorrelated events distributed according to Poisson statistics. If…
Homing in for New Year: impact parameters and pre-impact orbital evolution of meteoroid 2014 AA
On 2008 October 7, small asteroid 2008TC3$2008~\mbox{TC}_{3}$ turned itself into the parent body of the first meteor ever to be predicted before entering the Earth’s atmosphere. Over five years…
Far from random: dynamical groupings among the NEO population
Among the near-Earth object (NEO) population there are comets and active asteroids which are sources of fragments that initially move together; in addition, some NEOs follow orbits temporarily…

The Chelyabinsk superbolide: a fragment of asteroid 2011 EO40?
Bright fireballs or bolides are caused by meteoroids entering the Earth's atmosphere at high speed. On 2013 February 15, a superbolide was observed in the skies near Chelyabinsk, Russia. Such a…
The orbit of the Chelyabinsk event impactor as reconstructed from amateur and public footage
A ballistic reconstruction of a meteoroid orbit can be made if enough information is available about its trajectory inside the atmosphere. A few methods have been devised in the past and used in…
The trajectory, structure and origin of the Chelyabinsk asteroidal impactor
TLDR
An analysis of selected video records of the Chelyabinsk superbolide of 15 February 2013 found that its orbit was similar to the orbit of the two-kilometre-diameter asteroid 86039, to a degree of statistical significance sufficient to suggest that the two were once part of the same object.

Chelyabinsk Airburst, Damage Assessment, Meteorite Recovery, and Characterization
TLDR
The asteroid impact near the Russian city of Chelyabinsk on 15 February 2013 was the largest airburst on Earth since the 1908 Tunguska event, causing a natural disaster in an area with a population exceeding one million.
On the dynamical evolution of 2002 VE68
The minor planet 2002 VE68 was identified as a quasi-satellite of Venus shortly after its discovery. At that time its data-arc span was only 24 d; now it is 2947 d. Here we revisit the topic of the…
Earth-viewing satellite perspectives on the Chelyabinsk meteor event
TLDR
Satellite observations of the Chelyabinsk superbolide debris trail, collected within minutes of its entry, demonstrate the general ability of Earth-viewing satellites to provide valuable insight on trajectory reconstruction in the more likely scenario of sparse or nonexistent surface observations.
Reconstructing the orbit of the Chelyabinsk meteor using satellite observations
The large number of objects in a range of orbits around the Sun means that some will inevitably intersect the Earth, becoming a meteor. These objects are commonly comet fragments or asteroids. To…
The Location of Linear Secular Resonances for Semimajor Axes Smaller Than 2 AU
Abstract In this paper, we present the location of linear secular resonances in the region of semimajor axesaless than 2 AU, where many near-Earth asteroids (NEAs) are or shall be found. The results…
The impact and recovery of asteroid 2008 TC3
TLDR
A dedicated search along the approach trajectory recovered 47 meteorites, fragments of a single body named Almahata Sitta, with a total mass of 3.95 kg, identifying the asteroid as F class, now firmly linked to dark carbon-rich anomalous ureilites, a material so fragile it was not previously represented in meteorite collections.
